Outdoor images get corrupted due to fog and mist. Many techniques have been adopted to obtain to solve this problem but no such optimum solution is reached since each image has its own unique features. Dark channel prior method gives a significant idea about the amount of airlight responsible for the formation of haze. Dark channel with contrast controller and sky masking improves the visibility and...
Detecting fish in submarine environment is a challenge due to the properties of the water such as light absorption and scattering. In this work, we present a method for preprocessing images in submarine environment. In the first step, we model the underwater environment as overlapp of two processes. The first process is considered as a Poisson distribution, while the second one is considered as a...
Median filter was once the most popular nonlinear filter for removing impulse noise because of its good denoising power. In this paper, we present a novel adaptive fuzzy median filter to the restoration of salt & pepper impulse noise-corrupted image, which is particularly effective at removing highly impulsive noise. First we estimate noise level based on fussy set theory, then process the corrupted...
